To all wlwm it may comm-n;

Be it known that I, Isaac VANDEN Bronx, a citizen of the United States,(residence and post-oflioe address, 51 East Twentyfifth street,Manhattan, New York city, New York,) have invented certain new'anduseful Im rovements in the Art of Making Hydrocar on Soaps, of which thefollowing is a specification.

There have heretofore been known and in some forms commercially usedsoaps containin volatile hydro-carbon oils such as na ht a.

he object of the present invention is to make in a simple and economicalmanner a better soap of this character and one which shall better retainthan heretofore the hydrocarbon oil notwithstanding. its volatilenature.

To these ends I manufacture 'my soap as follows: I procure commercialpotash lye, tallow, cocoanut oil or the equivalent, and a comparativelysmall quantity of pure soap free from acids, such as good castile soap,or in lieu of this last I may make such pure referred form of myinvention proceed as ollows: I take say one hundred grams of the puresoap and dissolve it in one kilogram of water, preferably at atemperature of abou 120 Fahrenheit maintaining this tempera are throbout the rocess. Ithen mix with this so ution w e stirring, ten grams ofammonia of, say, ninety six per cent. s ecific gravity, andinto this Istir gradua y a small constant stream" of kerosene and naphtha in equalparts, or of kere sene and naphtha mixed, as aforesaid, preferably usinga hollow stirrer through-which the stream may be introduced until I haveincorporated about one hundred kilograms.

The hydrocarbon is preferably passedthrough a heated coil so it reachesa temperature of about 120 before passing into the soap emulsion. Forconvenience I will call this my hydrocarbon emulsion. I also take, say,thirty kilograms of the tallow and thirty kilograms of the cocoanut oiland melt the same by heat. I introduce in a stream thirty kilograms ofpotash lye 36 Baum, maintaining ,the heat referably between 120 and 140.To the a ali soa so formed I now add about ten kilograms o thehydrocarbon emulsion, using a hollow stirrer and suificient head orpressure so as to conduct the emulsion down into the mass and stir it asp ifi ti n or mm m Patented May 31, 1910.

into it adually, allowing the mass to cool. Prefer-filly I employcooling coils so as to reduce the temperature rapidly and check theevaporation of the hydrocarbon. As the mass cools it breaks up into alumpy solid mass which is then thereafter preferably ground or furtherbroken up into grannlated form. In this granulated form I box it andship it. The product so obtained forms excellent and pure hydrocarbonsoap of detergent quality and without the presence of adulterants suchas are commonly present in the cheaper grades of soaps,

now on the market. The volatile hydrocarbon is incorporated-and held ina manner which, so far as I am aware, is peculiar to this process. I amnot able to statewhetber the action of the ammonia is a purely chem icalaction upon the soap or a .catalytic action in the process, therelativelysifiall quantity used in proportion to the other bodiespresent indicating to me the possi bility of the latter.

As it is conceivable that this product may be made by other processes,Iclaim the productas an article of manufacture, in my copendingapplication-No. 377,507, filed herewith, separately from the process bywhich it formed, the present application being for the particularprocess.

What I claim and desire to secure by these Letters Patent is 1. Theimprovement in the art of making hydrocarbon soaps, which consists infirst emulsifying the hydrocarbon with soap and the aid of a relativelyminute quantity of ammonia and then gradually stirring it into aheated'mass of' soap and cooling the same.

2. The improvement in the art of making hydrocarbon soaps, whichconsists in first emulsifying the hydrocarbon with a dilute solution ofsoap containing a small quantity of ammonia and then gradually stirringit into a heated mass of soap and cooling the siameaand then granulatingthe-mass so prouce 3. The improvement in the artof making.

step 0 hydrocarbon soaps, comprising the drocarbon into a solution ofsoa containing approximatel ten parts by weight of soap to one part 0ammonia water at a temperature a proximating one hundred and twentyegrees Fahrenheit.

5. The improvement in the art of making hydrocarbon soaps, comprisingthe step of emulsifying a volatile hydrocarbon consisting largely ofnaphtha by stirring the hydrocarbon into a solution of soap containingapproximately ten parts by weight of soap to one part of ammonia waterat a temperature approximating one hundred and twenty degrees Fahrenheitand continuing the addition of hydrocarbon until at least one hundredparts thereof for each part of soap are present.

6. The improvement in the art of making hydrocarbon soaps, comprisingthe step of emulsifying a volatile hydrocarbon consisting largely ofnaphtha by stirring the hydrocarbon into a solution of soap containingapproximatel ten parts by weight of soap to one part 0 ammonia water ata temperature approximating one hundred and twenty degrees Fahrenheitand the subsequent step of stirring and mixing such emulsion graduallyinto a mass of soap in the liquid state and to an extent not exceedingfifteen percentum of the emulsion relatively to the mass of soap byweight.

7. The improvement in the art of making hydrocarbon soa s, comprisingthe step of making an emulsion of volatile hydrocarbon with an aqueoussolution of approximately ten parts by weight of soap to one hundredparts by weight of water to which has been added approximately one partof ammonia water.

8. The improvement in the art of making hydrocarbon soaps, comprisingthe step of emulsifying volatile hydrocarbon, consisting largely ofnaphtha by stirring it into an aqueous soap solution in a substantiallyneutral or but very slightly alkaline condition and at a temperature ofapproximately Ione hundred and twenty degrees Fahreneit.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
